Question

If Juanita and her friends made nine friendship bracelets in three hours, how many bracelets could they make in 15 hours? Which proportion could be used to find x , this number of bracelets?

Answer 1

45 bracelets

Explanation:

If Juanita and her friends made nine friendship bracelets in three hours, how many bracelets could they make in 15 hours?

Let the number of bracelets that could be made is 15 hours = x

The proportion that could be used to find x , this number of bracelets is given as:

Number of hours/ Number of bracelets made

= 3/9 = 15/x

Cross Multiply

= 3 × x = 9 × 15

= 3x = 9 × 15

x = 9 × 15/3

x = 45 bracelets

Therefore, the number of bracelets that could be made = 45 bracelets
